 Presentation Notes

There are many diverse geotechnical problems where reliable predictions of ground deformations are critical in design and only limited options are available to control these movements. This lecture will compare and contrast experiences in the application of advanced constitutive models in the prediction and control of ground movements in four distinct classes of problem:  urban excavations, mechanized tunneling, seismic retrofit of waterfront structures, and long-term prediction of settlements on clay.

 Speaker Biography:

Andrew J. Whittle, the Edmund K. Turner Professor of Civil and Environmental Engineering at MIT, has been selected as the 2017-2018 Cross-USA Lecturer for the Geo-Institute of the American Society of Civil Engineers.

Dr. Whittle earned his BSc. (1st class honors) in Civil Engineering from Imperial College in 1981 and Sc.D in Geotechnical Engineering at MIT (1987). He joined the MIT faculty as an Assistant Professor in 1988, became a Full Professor in 2000 and has served as Head of the Department of Civil and Environmental Engineering, 2009-2013. Dr. Whittle is an expert in geotechnical engineering. His research deals principally with formulation of constitutive models for representing the complex mechanical properties of soils and their application in predicting the performance of foundations and underground construction projects. His research has been widely used in the design of foundation systems for deepwater oil production facilities and in major urban excavation and tunneling projects including the Central Artery-Third Harbor Tunnel in Boston, and Tren Urbano in San Juan, Puerto Rico. Most recently he has led research efforts in the application of wireless sensor networks for monitoring underground water distribution systems and construction projects. He serves as Chief Scientific Advisor for an associated spin-off company, Visenti Pte., Ltd. that provides smart water analytics services (acquired by Xylem, Inc. in 2016).

Dr. Whittle is a co-editor of the International Journal of Numerical and Analytical Methods in Geomechanics (since 1999). He is an active consultant who has worked on more than 30 major onshore and offshore construction projects and was an expert involved in the investigations into the collapse of the Nicoll Highway in Singapore (2004-2006). He has also served on a series of major review panels including for the National Research Council and National Academy of Engineering (NRC/NAE) investigating the performance of hurricane protection systems in New Orleans, for the Governor of Massachusetts on a ‘stem-to-stern’ safety review of the Big Dig tunnels in Boston, for the Chief Executive of Hong Kong investigating the delay in the works of the Hong- Kong section of the Guangzhou-Shenzhen-Hong Kong Express rail link (XRL), and as a member of the Board of Directors for the Massachusetts Department of Transportation (2009-2015).

Dr. Whittle has published more than 200 papers in refereed journals and conferences and received several awards for his work from the American Society of Civil Engineers, including the Casagrande Award (1994), the Croes Medal (1994), the Middlebrooks Prize (1997, 2002, and 2005) and the Huber Research Award (1998).

 Presentation Notes
The proposed bridge is a three-span bridge over Christina River in Wilmington, Delaware. It is approximately 470-ft long and 45-ft wide. The subsurface soils along the approaches to the bridge on both sides of the river consist of contaminated, very soft, fine-grained soils extending to a depth of up to 40-ft below the existing ground surface.

The main geotechnical challenge on the project was the design of the approach embankments. The design had to consider the settlement of the foundation soil, downdrag on the bridge foundation due to the settlement, global stability, stability during flood events, and lateral squeeze. Multiple alternatives were evaluated and different solutions proposed for each approach. Construction is currently underway.

Design team geotechnical engineers will present on the design of the Christina River Bridge's approaches - one with EPS geofoam and the other with conventional mechanically stabilized earth on controlled modulus columns.

Eric M. Klein, P.E., D.GE is a Senior Manager with RK&K. Bibek B. Shrestha, P.E. is Senior Project Engineer with RK&K.

 Presentation Notes

The Dulles Silver Line Phase II (DSP2) is an 11.4 mile extension of the Washington Area Metro Transit Authority’s Silver line. The three miles of elevated guideway lies within the Culpeper Fault Basin, a geologic feature within the Piedmont Region that was formed during the Triassic Geologic Age.  


Very large lateral loads are produced along the guideway by transit braking, rail temperature, and centrifugal forces on curves. These lateral loads produce large moments at the foundation level due to the height of the guideway. An evaluation of various foundation systems was performed and mono-drilled shafts, socketed into rock, were selected to provide the most economical support of the aerial guideway. Vertical loads are resisted by side friction and end bearing in the rock socket, while moments and lateral loads are resisted by the stiffness of the shaft and the rock socket. The large lateral loads and moments produce very large shear forces in the shafts at the rock interface.  

A load testing program consisting of, three O-cell axial load tests and three lateral load tests were performed on test shafts instrumented with strain gauges, extensometers, and inclinometers. The challenge in developing the load testing program was how to reproduce the effects of the extremely high design loads along the test shafts, considering the practical limitations of the load test equipment. The process of developing and executing the load tests, and analyzing the test results will be discussed.

Bill Billiet, P.E., is an Associate Engineer with Schnabel Engineering.

 Presentation Notes

A Tale of Two Stabilizations

Collectively, these two case histories illustrate how the specific conditions of a particular slope or landslide stabilization project necessitate creative approaches to a design and construction solution in addition to the value of a collaborative problem solving approach between engineer and contractor.

 Old Croton Trailway Stabilization

 In March 2015, a 185 year old gravity stone retaining wall supporting a 50 foot slope failed, resulting in a landslide of approximately 500 cubic yards of fill, glacial till, boulders, and deleterious materials. The landslide debris collided with an 8-story, 100-unit apartment building and exposed the historic (inactive) Croton Aqueduct. The building was immediately evacuated and temporary stabilization was provided by the local fire department. The New York Office of General Services invited Moretrench American Corp. to work on the emergency design-build team to stabilize the slope, protect the buildings above and below the slope, and rebuild the wall.

 Stabilization of S.R. 38 Emlenton Hill Improvements

As part of the reconstruction of S.R. 0038, Section A00, a roadway fill was constructed to accommodate realignment of S.R. 0038 between the I-80 Exit 42 interchange and the S.R. 0268 intersection near the bridge over the Allegheny River into Emlenton Borough. Structural retaining walls were constructed to support the realigned roadway along the steeply sloped hillside. The tallest of these walls consists of a tied-back soldier pile retaining wall requiring embedment into rock. Finite element models were created for each design height to analyze construction staging for the unique bottom up construction.

 This project case history discusses the intricacies of the wall design along with some of the challenges associated with its location along the steeply sloped hillside and includes the construction process, specialty equipment and unique procedures which were required to install the soldier piles, steel wales and the rock anchors using bottom-up construction methods.

 Speaker Biography:

Mr. Bennett has been involved in the design and management of specialty geotechnical construction projects throughout the Mid Atlantic United States for over 20 years. He specializes in the design and analysis of deep foundations, ground anchors and anchored structures primarily focusing on tieback walls, soil nailing, micropiles, drilled shafts, augercast piles, foundation underpinning, tiedowns and grouting for structural support. Mr. Bennett earned his BS and MS degrees in civil engineering, specializing in structures and soil mechanics, from West Virginia Institute of Technology and has completed a Master of Engineering and Technology Management degree from George Washington University. He is a registered Professional Engineer, an active member of ADSC, ASCE and DFI, and sits on a number of industry technical committees including the ADSC/DFI Micropile Committee (Immediate Past Co-Chairman), the ASCE Geo-Institute Earth Retention Systems Committee , and DFI Tiebacks and Soil Nailing Committee (Past Chairman).

Mr. Bennett serves as Business Development Manager for Moretrench American Corporation in the Mid-Atlantic and Midwest regions of the United States.
